The understanding and appllication of fatigue crack propagation mechanism in variable amplitude loading is very important for life prediction of the air travel structures. Particularly, the retardation and arrest behavior of fatigue crack propagation by single tension overloading is essential to the understanding and appllication of fatigue crack propagation mechanism in variable amplitude loading.
Numerous studies of the retardation behavior have been performed, however investigations of the arrest behavior have not been enough yet.
As for the arrest behavior, Willenborg had reported that the overload shut-off ratio [R<SUB>so</SUB>=(K<SUB>OL</SUB>/K<SUB>max</SUB>)<SUB>crack arrest</SUB>] had been the material constant, but recently several investigators have reported that the overload shut-off ratio depends upon the stress ratio.
In this study, authors have investigated the effect of stress ratio on the threshold overload shut-off ratio to generate arrest of fatigue crack growth in high tensile aluminum alloy 7075-T735 which have used in material for air travel structures, It has been -0.4?R?0.4 till now, the region of stress ratio investigated.
The threshold overload shut-off ratio has decreased as stress ratio has increased in overall region of -0.4?R?0.4 and the linearity has been seen in this material. Moreover, the experimental equation between R<SUB>so</SUB> and R has been made; The relation has been R<SUB>so</SUB>=-R+2.6.
